This major release introduces Smart HTML Attributes, strict_types by default, and several syntax improvements. It requires PHP 8.2+.

Smart HTML Attributes * Null values: Attributes with null values are now dropped instead of rendering as empty strings. * Boolean attributes: Attributes like checked or disabled render conditionally based on truthy/falsey values. * Array support: class and style attributes now accept arrays (e.g., class="{[active: $cond]}"). * Data attributes: data-* attributes automatically JSON-serialize non-string values (arrays, objects, booleans). * Aria attributes: aria-* attributes render boolean values as "true"/"false". * Type checking: Passing invalid types (arrays, objects) to standard attributes now triggers a warning and omits the attribute.

New Features * Added n:elseif support. * Added nullsafe filter operator ?| (e.g., {$var?|upper}). * Added |toggle filter for manual boolean attribute control. * Support for unquoted n-attribute syntax: n:if={$cond}. * Added Engine::setMigrationWarnings() to help detect changes in attribute rendering.

Breaking Changes & Deprecations * strictTypes is now enabled by default. * Using $this and $__* variables in templates is deprecated. * The undefined unsafe operator ??-> is deprecated (use ?->). * Global constants should now be prefixed with a slash (e.g., \PHP_VERSION). * Engine::addFilterLoader() is deprecated.
